Wore some lab goggles and long sleeves and basically played like paintball games. We got away from doing it after one person brought a pellet gun and a couple of those had to be dug out of skin. Jerk didn't stick to the one pump rule...

One guy took a pellet in the calf and then dug it out with a fork in his kitchen while we watched. He was a Christian Scientist and wouldn't see a doctor so he operated on himself. One of the more gross things I had seen up to that point in my life.
